0: Positive
Set C1.15 to 0 if the motor speed is required to be
increased with the increase of the reference.

Set C1.15 to 1 if the motor speed is required to decrease
with the increase of the reference.

This function can make the close-loop regulation enter
stable status quickly.
When the close-loop function is enabled, the frequency
will ramp up to the preset close-loop frequency (C1.17)
within the Acc time, and then the drive will start
close-loop operation after operating at the preset
frequency for certain time(defined by C1.18).

Note:
You can disable the function by set both C1.17 and
C1.18 to 0.
